Install Mint with 32bit UEFI

Post by kjh61 » Thu Mar 10, 2016 6:04 pm

I want to install Mint 17.3 on an ASUS X205TA which has a 64 bit Atom processor but uses 32 bit UEFI to boot. There is no legacy boot option so can't boot using BIOS. From searching the web, there are a few users that have overcome this by hacking the install media, but I am not yet confident of this. I was wondering whether Mint version 18 is likely to include 32bit UEFI support for this type of Atom processor in either the 64bit or 32bit distributions?

I hadnt heard of 32-bit UEFI before, but yeah apparently it happens.
This thread on the forum may help you :
viewtopic.php?t=204961&p=1065977

the problem is to install a 32-bit bootloader. The op in the previous thread had to follow complicated steps to get grub working.
Maybe it might have worked directly if he had installed a 32-bit Mint ISO (though obviously he would have a 32-bit OS, so not exploiting fully his 64-bit processor).
An alternative would be to install the 32-bit version of refind : refind_ia32.efi
Then you install Mint 64-bit without bootloader (with "ubiquity -b" in a terminal) and refind will automatically find the linux kernel.

I've been researching this for the past week or so (am new to Linux) having been trying to repair a Linx 7 tablet and have found that a GPT-formatted USB with a 64-bit Mint 17.3 distro will boot (via GRUB) on UEFI once you've copied "bootia32.efi" to the EFI/Boot directory. 32-bit will boot if you copy the BOOT and EFI directories from the 64-bit ISO to the 32-bit media and then copy the "bootia32.efi" file as above (you'll get GRUB with the 32-bit options).

I will provide a link to the file if it's ok to do so but it's not too hard to find once you know what you're looking for!

I'll provide more details later as I intend to start a thread on the Linx but will add that you have to be patient .. it takes the display time-out period once booted (at least 10 minutes) before you should move the mouse or press anything otherwise the display won't appear. I probably need to edit the startup commands to overcome this.

I have attempted an install to the MMC but it won't work unless I install the bootloader on the internal SSD which I won't be doing for another week or so, as I wish to un-bork the original Win8.1 install first and take a proper image.

Hope this is of some relevance; what system(s) are you using? I used Win7 with the command prompt and RUFUS to create the installation media.

Thanks for your ideas, guys. For the install media I am running a Win10 laptop and used universal-usb-installer to create a Mint USB stick to boot from. See http://www.pendrivelinux.com/universal- ... -as-1-2-3/

Maybe these instructions for installing Ubuntu on the x205ta can work just using the Mint ISO instead?...
https://github.com/lopaka/instructions/ ... -x205ta.md

There are various things (wifi, audio, etc.) that either don't work or you have to jump through hoops like upgrading drivers and the Kernel version, so be sure to do searches for "x205ta", "Intel Atom", "atom", "z3735", "bay trail", etc. Many people on this forum and others have attempted this. It does not look easy at all.

Hi,

you can use my tutorial to make an usb bootable disk with Linux Mint 17.x for 32bit UEFI mode.

Here is my tutorial : viewtopic.php?f=42&t=216857

The issue with some of these devices is that they appear to require a GPT disk with NTFS partition for the OS. In the case of the tablets (BayTrail) an option for CSM does appear but I've not been successful so far in getting it to boot in this mode. These also refuse to boot from a DVD.

Live USB Mint 17.3 & LMDE 32-bit and 64-bit editions all boot (eventually) but so far haven't gotten persistence working. Presumably an install should work as long as you make sure the necessary files are there (as with the USB). As mentioned by bbaker6212 getting the hardware to work properly will be a challenge; a wi-fi dongle may well come in useful.

Hi...many thanks for the responses so far. I have got as far as getting a 64 bit version of Mint 17.3 to boot using a boot1a32.efi on a USB stick, but then encountered some of the reported hardware issues, the most obvious one being the lack of WiFi. I appreciate the comments, all very helpful. But I am still wondering if anyone knows the answer to my original question, which is whether this is type of processor is likely to be better supported in Mint version 18? :D
